Introduction: Palmaris longus is a slender, fusiform muscle lying medial to flexor carpi radialis. It arises from the medial epicondyle of humerus by the common tendon, and from adjacent intermuscular septa and deep fascia of the arm. Palmaris longus is often absent on one or both sides.
Aim of the Study: To determine the incidence of unilateral and bilateral absence of palmaris longus in the north Karnataka region.
Materials and Methods: Dissection of 30 embalmed adult cadavers (60 upper limbs) of both sexes belonging to north Karnataka region were carried out and observed for the presence or absence of palmaris longus muscle.
Results: Bilateral absence of palmaris longus was observed in 2 cadavers (1 male and 1 female). Unilateral absence was observed in the right side of 1 male cadaver.
Conclusion: The incidence of absence of palmaris longus muscle in the north Karnataka region will be useful to surgeons doing tendon graft surgeries.
